"I can't help but wonder why he doesn't just use the second transmission for shifting ?

The shifter handle for that transmission is within easy reach right in front of him."

Not Sure,

Maybe the second trans is only used as a Hi / Lo setup. I hadn't thought of that until you said it, but that opens up some interesting gear options with 2 trannys.

I agree with you though. I would try to run that chain drive as slow as possible and use the gearing in the lower gearbox.

It seams to me that with the second transmission set up like it is the front two speed transmission could be used as the " high & low " and that would then leave the 3-speed transmission for driving the tractor.
